P432 Report Phase Consultation

This Modification proposes to align the BSC definition of an Advanced Meter with that in the Standard License Conditions (SLC) and to set explicit Half Hourly (HH) Settlement obligations for Current Transformer (CT) Advanced Meters ahead of the migration to Market-wide Half-Hourly Settlement (MHHS). 

Summary

Market-wide Half-Hourly Settlement (MHHS) requires that all Metering System Identifiers (MSIDs) are settled on a Half Hourly (HH) basis and moved to the MHHS Target Operating Model. The Code Change and Development Group (CCDG) has recommended moving Current Transformer (CT) Advanced Meters to settle HH by October 2023 in its consultation on the Transition Approach for MHHS. If this recommendation is not implemented the risk is that there will be insufficient time for Customers, Suppliers and their Agents to address issues that may arise will be increased, especially against the backdrop of the larger MHHS migration activities that will be needed for smart Meters.

• Inconsistent definitions of Advanced meter in the BSC versus Electricity Supply Standard Licence Conditions; and
• The risk of not meeting MHHS Transition Timetable leading to Settlement errors.

P432 seeks to align the BSC definition of an Advanced Meter with that in the SLC and to set explicit HH Settlement obligations for CT Advanced Meters ahead of the migration to MHHS. Existing CT Advanced Meters settling NHH are expected to migrate using the Change of Measurement Class (CoMC) process to settle HH by October 2023 and all new connections for CT Advanced Meters will be expected to settle HH from October 2022. Any opt-out/in rights for customers under the SLC are reflected in the P432 solution.
